Sounds like a good idea. Did they say if sleep (or lack thereof) affects this at all? Were there any things that they thought you could do to help with possibly recovering the sight you have lost?
Blood pressure can be a problem. Working 72 hours at work causes higher blood pressure. In fact, in the eye docs office was the first time I've ever had a doc tell me my blood pressure was high. Usually they comment how low it is.
Probably didn't help me when I was clearing all them branches on Saturday. Might have caused the eye problem Sunday, and I didn't notice cause I was in bed all day.
